Are you by chance using .NET Core? I noticed that this issue is specifically related to the fact this project wasn't compiled against Core. I have no problems using .NET Standard.

I have this too in .NET 5 WPF

davlovsky commented 2 years ago

Same here. Winforms, after migrating from .NET Framework to .NET 5.

PhilippElhaus commented 2 years ago

Switched to the latest NuGet of WebSocket4Net - is similar to code and works just fine.

davlovsky commented 2 years ago

I had this line in my old code: Websocket.SslConfiguration.ServerCertificateValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };

Do you know if there is a WebSocket4Net analog?

One workaround is to use Connect instead of ConnectAsync and Send instead of SendAsync and if that doesn't work for you switch to https://github.com/sipsorcery/websocket-sharp

With a .Net6 project, I used Close instead of CloseAsync and no longer had this error. Using Connect and Send as well, thanks to @henon.
